I had a couple of free days and of course this was a great opportunity to finish my assigment. Three long days and I got everything ready for upload. In overall drawing diagrams and writing assumptions won't take that long, but research work was more time consuming. Maybe 60-80 hours totally...
I'm still feeling a little uncertain about my TransMaster solution with just stateless session bean and DAO... and I'm not sure that creating user account via entity bean was that a good idea with container managed security... And one extra object in a corner of a sequence diagram (which I noticed after upload) .
Anyway, thanks guys (especially Parag), this forum has been a big help. If I fail I just have to get back to you for more second opinions.
Tomi, I wish you the best and I know you are SCEA material I am still caught in the mire of sequence diagram..so a long way to go before i submit..i will be posting questions on component diagrams soon..so am looking forward to help from you, as always
